Working in Silicon Valley means asking yourself if this thing you’re seeing is a new Google ISR platform or that rapture everyone is talking about, but pretending it’s perfectly normal and going about your day regardless.

This is also how tech media often covers security. No one panic reads stories about inventory and patch management, so those don’t get a lot of play…

Modeling and Sizing Security Orgs
One of the hardest things for leaders in the Security space is justifying team sizes and budget. So, I thought I’d share some perspectives on this. Part 1 (Probably)

A great thread. I’d add, as a practical observation: Very few organizations understand how to think about Security as part of their business; Even less understand Trust and Safety. A lack of proactive T&S strategy is unacceptable, but honestly unsurprising.

Me: I've seen things you people wouldn't believe. Attack ships on fire off the shoulder of Orion. I watched C-beams glitter in the dark near the Tannhäuser Gate. All those moments will be lost in time, like tears in rain. Cashier: Sir, again, American Girl dolls are not in anyway sentient.

CISOs are offered loads of free stuff (Dinners, Sporting Event Box Seats, Whiskey Tastings, etc) and most of us say no because they might create the appearance of a conflict. NO ONE is getting offered free PJ Trips as a normal thing that wouldn’t give the appearance of impropriety.
